I just installed a Truxedo roll-up and it's great..takes about 30 seconds to roll it up, velcro straps to secure it..and off ya go....needed some xtra weather stripping by the bulkhead coz of the bedcaps, but a simple, functional, good looking option..

 

i have a tonnuea cover on my f150 glasstite breeze alittle heavy perfect for the rainy/snow season adds just enough weight. but if i were to do it again i would get the black plastic ones. its lighter and even one caveman can remove it by himself. www.glasstite.com

 

I have the Pace Edwards Jackrabbit. It's retractable and it locks to prevent anyone from getting in. It's a bit more costly than other types of covers....like the velcro type; but it fits flush with the bed and looks nicer. IMO.
